[Dovecot] default domain empty

[Leo Unglaub]

Hi, thanks for your answer.
>so, if you put in auth_default_realm, your default domain, it will append this to the username.
i already found this option in the documentation, but it only works on
the login. The login process is using the new auth_default_realm, but
the variable %d is empty. in the mail_localtion.

My dovecot version is
>mail:/etc/dovecot# dovecot --version
>1.2.11

Is there a other solution for this?
Thanks a lot
Greetings Leo
